This will be your first day, right? I do think you’re overthinking it a bit.
Since you’ll be at DL for a MM, you’ll be able to pull an 8am return time FP (I’d pick Space, personally), and then you’ll be able to pick a new FP at 8 (I’d probably do Matterhorn or Star Tours), then, assuming that return time is pretty quick, you’ll likely be able to pull one more on the DL side if the timing works out - then grab RSR around maybe 9:30 or 10. Or you could grab it earlier, just depends how your morning is flowing and what return times look like... but I’d say you can easily fit two DL FPs in before you pull RSR.
I’d personally start in Fantasyland during the MM, head to Tomorrowland once you’re done there, and then just follow the FPs or the low-wait rides around until your breakfast!
You don’t have to fit all the rides in one day since you have multiple days, so don’t stress! And you may get some cancelled FPs that will make things easier, too.
